2002 4.0 SOHC Seafoam insertion point.

[bigred85]

I have read all the posts, and seen many of the pics on a sea foam insertion point. But It does not resemble what my engine looks like. Does anyone have any clear pics of the 2002 4.0 SOHC and where I should insert the SEAFOAM? thanks ! I am most confused on which vacuum line is which. (i need a proper service manual yes) New to this site, and new to tinkering with my Explorer. Thanks!

Welcome to this forum! I've moved your thread into the stock 2002-2005 section. The vacuum lines are interconnected, so it should enter the engine from any point. A large line such as the one used on the power brake booster should work fine.

That's what I used to suck in about half a can. Suck it in, let it sit for an hour or so, then go start it up and watch the smoke show.
